Finite element methods with B-splines by Klaus Höllig ( )
11 editions published between 2003 and 2010 in English and held by 452 WorldCat member libraries worldwide
Finite Element Methods with B-Splines describes new weighted approximation techniques, combining the computational advantages of B-splines and standard finite elements. In particular, no grid generation is necessary, which eliminates a difficult and often time-consuming preprocessing step. The meshless methods are very efficient and yield highly accurate solutions with relatively few parameters. This is illustrated for typical boundary value problems in fluid flow, heat conduction, and elasticity. Topics discussed by the author include basic finite element theory, algorithms for B-splines, weighted bases, stability and error estimates, multigrid techniques, applications, and numerical examples
Box splines by Carl De Boor ( Book )
11 editions published between 1993 and 2010 in English and Undetermined and held by 394 WorldCat member libraries worldwide
This book on box splines is the first book giving a complete development for any kind of multivariate spline. Box splines give rise to an intriguing and beautiful mathematical theory that is much richer and more intricate than the univariate case because of the complexity of smoothly joining polynomial pieces on polyhedral cells. The purpose of this book is to provide the basic facts about box splines in a cohesive way with simple, complete proofs, many illustrations, and with an up-to-date bibliography. It is not the book's intention to be encyclopedic about the subject, but rather to provide the fundamental knowledge necessary to familiarize graduate students and researchers in analysis, numerical analysis, and engineering with a subject that surely will have as many widespread applications as its univariate predecessor. This book will be used as a supplementary text for graduate courses. The book begins with chapters on box splines defined, linear algebra of box spline spaces, and quasi-interpolants and approximation power. It continues with cardinal interpolation and difference equations, approximation by cardinal splines and wavelets. The book concludes with discrete box splines and linear diophantine equations, and subdivision algorithms

B-splines without divided differences by Mathematics Research Center (United States. Army) ( Book )
6 editions published in 1985 in English and Undetermined and held by 5 WorldCat member libraries worldwide
This note develops the basic B-spline theory without using divided differences. Instead, the starting point is the definition of B-splines via recurrence relations. This approach yields very simple derivations of basic properties of spline functions and algorithms

The result of this paper is a generalization of an characterization of the limits of multivariate cardinal splines. Keywords: Convergence; fourier transforms; Analytic functions; Convolution; Exponential functions; Fourier series

A Diffusion Equation with a Nonmonotone Constitutive Function by Mathematics Research Center (United States. Army) ( Book )
2 editions published in 1982 in English and held by 2 WorldCat member libraries worldwide
In this report we first review known (previously unpublished) a priori estimates for (P), and we then give a simpler construction for the existence of infinitely many solution of (P) for a piecewise linear phi as suggested by G. Strang. we then investigate further the qualitative behavior of solutions of (P). Motivated by known results in one space dimension for the steady state, non-elliptic problem, we study the analogous convexified problem associated with (P). Analytical and numerical considerations suggest that the unique solution of the convexified problem (which has a monotone, nondecreasing constitutive function) can be interpreted as an average of solutions of (P), whenever the data f'(.) reach the critical range
Minimal support for bivariate splines by Mathematics Research Center (United States. Army) ( Book )
3 editions published in 1986 in English and held by 2 WorldCat member libraries worldwide
In earlier works the authors applied their results on box-splines to analyze the approximation properties of bivariate smooth piecewise polynomials on the three direction mesh. In this report they obtain similar results for the other natural triangulation of R sub 2 which is generated by four directions. In particular they extend their results of minimality of support which are useful for constructing bases with good computational properties. Keywords: Numerical analysis
A Singular Free Boundary Problem by Mathematics Research Center (United States. Army) ( Book )
2 editions published in 1983 in Undetermined and English and held by 2 WorldCat member libraries worldwide
The Cauchy problem is similar to the well-known one phase Stefan problem (inone space dimension). In the latter one would assume g(x) = -1 for x <0, as well as g(x)> 0 for x> 0, so that g would have a jump discontinuity at x = 0. Our assumptions on the initial data g yield a different behavior of the solution v and of the resulting free boundary. Indeed, the free boundary is not (infinitely) differentiable at t = 0, contrary to the situation for the classical Stefan problem. This problem also serves as a prototype of nonlinear parabolic problems which arise as monotone convexifications of nonlinear diffusion equations with nonmonotone constitutive functions phi. That analysis shows the existence of infinitely many solutions v of the nonmonotone problem each having v bounded, but oscillating more and more rapidly as t infinity 0(+). Thus each solution v exhibits phase changes. Numerical experiments further suggest the conjecture that the physically correct solution of the nonmonotone problem is the one which for t> 0 sufficiently large approaches the unique solution of the appropriately related convexified monotone problem. This paper is another step towards the understanding of this intriguing phenomenon
